[EnergyPlus_Support] [Question] SingleDuct:ParallelPIU:Reheat

[Bing Dong <bingcat2007@xxxxxxxxx>]

Dear All,

I met a node connection error (it appeared as warning.) when I did SingleDuct:ParallelPIU:Reheat. Here is what I define.
I define Fan:ConstantVol as
SPACE1-1 PIU Secondary From Zone,  !- Air Inlet Node Name
SPACE1-1 PIU Fan Outlet; !- Air Outlet Node Name

And I define:

ZoneHVAC:EquipmentConnections,
SPACE1-1,                !- Zone Name
SPACE1-1Equipment,       !- Zone Conditioning Equipment List Name
SPACE1-1 Supply Inlet,   !- Zone Air Inlet Node or NodeList Name
SPACE1-1 PIU Secondary From Zone,         !- Zone Air Exhaust Node or NodeList Name
SPACE1-1 Zone Air Node,  !- Zone Air Node Name
SPACE1-1 Return Outlet;  !- Zone Return Air Node Name

The warning shows:
** Warning ** Node Connection Error for object UNDEFINED, name=SPACE1-1 PIU FAN
**   ~~~   **   UNDEFINED not on any Branch or Parent Object
**   ~~~   **   Inlet Node : SPACE1-1 PIU FAN OUTLET
**   ~~~   **   Outlet Node: UNDEFINED
** Warning ** Potential Node Connection Error for object UNDEFINED, name=SPACE1-1 PIU FAN
**   ~~~   **   Node Types are still UNDEFINED -- See Branch/Node Details file for further information
**   ~~~   **   Inlet Node : SPACE1-1 PIU FAN OUTLET
**   ~~~   **   Outlet Node: UNDEFINED

If I open the .bnd file, the nodes are all there and defined properly.
